Abstract

PURPOSE:To permit the flush surface formation by a simple raising and lowering mechanism by setting the radius of curvature of the lower part in the shape of the curved surface of a door glass larger than that of the upper part and installing a slidable member having the nearly equal radius of curvature to that of the upper part at the both side-edge parts at the lower edge and allowing said member to be slided. CONSTITUTION:The radius RL of curvature of the lower-part curved surface 4B of a door glass 4 is set twice the radius Rs of curvature of the upper-part curved surface 4A. Each radius of curvature of the curved surfaces of the curved pieces 16 and 17 of slidable pieces 14 and 15 at the front and rear edges 4b and 4c of the door glass 4 is set nearly equal to the radius Rs of curvature of the upper-part curved surface 4A. Said curved pieces 16 and 17 are fitted onto the rear rails 18 of a sash 5, having a weather strip 6 interposed, and the curved pieces 16 and 17 are slided vertically along the rail 18. With such constitution, the necessity of a complicated door-glass raising and lowering mechanism is avoided, and flush surface formation is permitted.

Description

[Detailed description of the invention] / 6 jp! -19 Hat4+ II+ /-LIII
Z1 The present invention relates to the structure of an automobile door glass and a door glass device including its guide structure.

(Prior Art) In recent years, in order to improve the aerodynamic characteristics of automobiles, attempts have been made to use Franche surfaces in various parts of automobiles. As part of this effort to create a flush surface, a door glass device has been proposed in which the door glass is formed into a composite spindle surface, and the difference in Vj between the door glass and the door outer panel is set as small as possible (Tokuko Showa). 5i, il 7044).

However, this car door glass device uses a lifting mechanism (window regulator) that sequentially selects the center of curvature of each spindle surface of the door glass as the center of rotation when raising and lowering the door glass. As a result, the structure of the elevating and lowering mechanism becomes cumbersome and complicated, and there is also the problem that smooth elevating and lowering cannot be achieved due to wobbling caused by changing the center of rotation.

[IR/nday θl] An object of the present invention is to create an id that does not require any complication of the door glass lowering mechanism when creating a 7 runner 7 ace between the door glass and the door outer panel. An object of the present invention is to provide an automobile door glass device having a structure.

(Structure of the Invention) In order to achieve the above object, in the present invention, the door glass is formed into a 1llI+III shape as a composite spindle surface in which the radius of curvature of the lower part is larger than the radius of curvature of the upper part, and the lower part of the door glass is A sliding contact member having a radius of curvature that almost matches the radius of curvature of the second part of the door glass and a curved piece that is continuous with the curved surface of the door glass is provided at both ends of the sliding contact member. The side ends of the two parts of the door glass which are continuous thereto are lowered by a guide member along a locus with a radius of 1'6 of curvature at the edge of the door glass.

(Effects of the Invention) According to the present invention, by increasing the radius of curvature of the lower part of the door glass, it is possible to create a flush surface with good opening to the door outer panel, and the door glass can be formed with a single radius of curvature. Since the door glass is lowered and lowered along the vertical locus of the door glass, there is no need to complicate the mechanism for raising and lowering the door glass, and the door glass can be lowered and lowered smoothly.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a door glass device according to the present invention is incorporated in a side door 2 of a two-door type passenger car 1, and seven run surfaces between a door outer panel 3 and a door glass 4 are installed. The goal is to

As shown in FIG. 2, the door glass 4 has an upper curved surface 4A having a radius of curvature RS, and a lower curved surface 4B having a radius of curvature R1 approximately twice the radius of curvature RS of the curved surface 4A.
It is formed as a composite spindle surface with a

By increasing the radius of curvature R1 of the lower curved surface 4B, it can be made closer to the radius of curvature of the second part of the door outer panel 3, as shown in the figure, and the step d between the door outer panel 3 and the door glass 4 can be reduced. It can be made as small as possible, and the side door 2 can be made into a flanche surface.

When this door glass 4 is in its outermost position, its top m4a and both greens 411.4 fit into the cloth strip 6 supported by the sash 5 of the side door 2, and the guide attached to the lower edge 4d. Bracket 7 seal play 1
- Weatherstrip outer and inner II, 12 fixed along the upper edges of the door outer panel 3 and the door inner panel 10, which constitute the door body 9, are located at the part 1; from the outside and inside. It is sealed to prevent water from entering.

As shown in FIG. 3, the door glass 4 labeled L is placed inside the internal space 13 of the side door 2 defined between the door outer panel 3 and the door inner panel 1°. - The radius of curvature Rcl of the curved surface 4A is descended along the approximately equal radius of curvature Δ1.

In order to raise and lower the door glass 4 along the raising and lowering trajectory A, the front and rear ends of the guide bracket 7 are provided along the front and rear side edges 4b and 4c of the door glass 4, as shown in FIG. 14. The front and rear slide pieces serve as two sliding members. +5 is integrally formed.

The front and rear entry ride pieces 14 and 15 have a frame portion 14a into which the side edges 4b and 4c of the door glass 4 are fitted.

A plate-shaped curved piece 1 protrudes with a predetermined width so as to be substantially continuous with the curved surface of the door glass 4 in the front and rear directions of the door glass 4.
0.17 is formed. The radius of curvature of the curved surfaces 16a, 17a of this curved piece 'Ci+17 is set approximately equal to the radius of curvature R3 of the upper curved surface 4A of the door glass 4.

And the curved surface 16a of this curved piece 16.17.

17a is the rear side rail 1 of the sash 5 as a member 141, as shown in FIG.
Open the weather strip 6 at 8, and then open the weather strip 6.
G1-Guided in the vertical direction while sliding in contact. The rail 18 as a guide member is formed into a curve having a radius of curvature approximately equal to that of the curved piece 17 in 1. Therefore, the radius of curvature is approximately equal to the upper curved surface 48 of the door glass 4. The sash 5 is also provided with a rail (not specifically shown) for guiding it.

These front and rear curved pieces]6. ] 7 is the n provided on the door glass 5 at the beginning of the lowering of the door glass 4 or at the later stage of the raising of the door glass 4.
As a result of being guided by the rear rail (18), the radius of curvature of the lower curved surface 4B of the door glass 4 is 1<1. is approximately equal to the radius of curvature R'S of the bipartite curved surface 4A.
It will be descended along descending locus A.

Further, after the middle of the descent of the door glass 4 or at the beginning of its ascent, the rear side edge 4c of the door glass 4 is guided by the rail 18, and therefore, the door glass 4 is moved during either the descent or the ascent. , the door glass 4 is guided along an upward/downward trajectory A that substantially matches the curvature of the upper curved surface 4A.

Because of this guide structure, the mechanism for lifting and lowering the door glass 4 can use almost the same structure as that of the well-known win l' regulator, although it is not specifically shown.
By locking one end of a pulling lever (not shown) of the lifting mechanism to an engaging portion 7a protruding downward from approximately the center of the guide bracket 7, the door glass 4 is moved along its lifting trajectory A. You can move up and down smoothly along the way.

In addition, in the bending guide structure, even though the radius of curvature R1 of the lower curved surface 4B of the door glass 4 is larger than the radius of curvature of the door outer panel 3, there is no interference in opening with the door outer panel 3. The door glass 4 can be stored within the interior space 13 of the door body 9.

As shown in FIG. 6, it goes without saying that the guide bracket 7' and the front and rear slide pieces 14' (the rear side is not shown) may be constructed separately.
